What is a frill?

What is a frill?

• A. A beak modification used for cracking shells.
• B. A tail feather arrangement used for display.
• C. A decorative or ornamental feature.
• D. A scale-like covering on the legs.

Answer: (C)

Frill is a decorative or ornamental feature. It describes a ruffled edge or frilly trim that adds visual appeal, like the lacey edging on clothing or the ornamentation you might see on some animals’ necks or bodies. It isn’t a specialized tool for feeding, nor a specific tail feather arrangement used for display, nor a scale-like covering on the legs. The term signals ornamentation rather than function.
